GEARING FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No; 738,991, datedSeptember 15, 1903. Application filed March 18, 1908, Serial No.148,371. (No model-l To all whom it may concern.-

Be it known that I, JOSEPH FAWELL, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented or discovered certain new and usefulImprovements in Gearing for Rolling-Mills, of which improvements thefollowing is a specification.

The invention described herein relates to certain improvements inuniversal mills, and has for its object a construction whereby theproper alinement between the vertical rolls and their drivingshaft maybe maintained, while permitting of the easy and quick removal of theshaft when desired. 4

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 shows in sectional elevation'portions of a vertical roll andits driving shaft with driving and alining connections. Fig. 2 is asectional elevation 011 a plane indicated by the line. II II, Fig. 1.Fig. 3 is a view similar to Fig 2, illustrating a modification of myimprovement. Figs. 4 and 5 are views similar to Figs. 1 and 2,illustrating a further modification.

In the practice of my invention the vertical roll 1 is provided with amiter-wheel 2, adapted to intermesh with a corresponding Wheel 3 on thedrivingshaft 4. The wheel 3 is provided with asleeve 5, extending somedistance alongthe shaft, so as to form a broad bearing for the wheel onthe shaft, and the wheel and shaft are so connected by a key 6 as topermit the wheel and sleeve to move along the shaft while rotatingtherewith. The sleeve is provided with flanges 7, extending around thesame and forming between them a seat for the reception of a concavesaddle 8, formed on a block 9. This block, as shown in Figs. 1 and'2, isadapted to project into a socket or recess formed in the miter-wheel 2and has a bearing against the side walls and bottom of such recess. Byreason of this construction the sleeve 5 and the miter-wheel 2,

which is formed integral with or secured to the vertical roll, arefirmly'locked together,

so as to prevent any such movements of the miter-wheels as will tend toseparate them. As shown in Figs. 1 and 2, the miter-wheel 2 is keyed tothe neck of the vertical roll 1, but may be formed integral with suchneck, as shown in Fig. 3. As the saddle extends only partially aroundthe sleeve, it will be understood that the shaft, with its sleeve andwheel, may be readily lifted from the saddle and out of connection withthe vertical roll and its miter-wheel.

As shoWnin Figs. 4 and 5, the saddle-block 9 may be provided with asocket or recess for the reception of a journal 10, formed on the upperend of the vertical roll.

It is characteristic of my improvement that the roll and itsdriving-shaft are always maintained in such alinement as to secure theproper engagement of the power-transmittin g wheels, and as the saddleis opened at its top, extending only partially around the sleeve, thedriving-shaft can be easily removed and replaced.

I claim herein as my invention- 1. A rolling-mill having in combinationa vertical roll, a driving-shaft, intermeshing miter-Wheels on said rolland shaft, an alining block engaging the roll and provided with anopen-topped saddle engaging the miter-wheel on the shaft, substantiallyas set forth.

2. 'A rolling-mill having in combination a vertical roll, adrivingshaft, intermeshing miter-wheels on said roll and shaft, analining block arranged in a recess in the miterwheel on the roll andprovided with an opentopped saddle engaging a peripheral seat in themiter-wheel on the driving-shaft, substantially as set forth.

In testimony whereof I have hereunto set my hand.
